I have send you guys a testdatabase with 33 doubles in it (about 100 games)

A nice horrordatabase "Crapbase 2.0" is placed on Dann Corbits site:
ftp://38.168.214.175/pub/a-openings/
ftp://38.168.214.175/pub/b-openings/
ftp://38.168.214.175/pub/c-openings/
ftp://38.168.214.175/pub/d-openings/
ftp://38.168.214.175/pub/e-openings/

Dann has cleaned as best ad he could with freeware tools. All doubles CB8 will
find are OR extra welcome detected games OR errors in the detection algoritm of
ChessBase.

Another nice trick is to dedupe it with Chess Assistent and look what it
finds.... ;-) Then dedupe with CB8 and look for differences...

Hint: Try to automate this process in some way so Mathias can check his
algorithm very thourougly and descent with very less time...

Kind regards,
